G.R. No. 63154 - People vs. Mawallil y Kars

Sukarno Mawallil and Sophia Sera were married in 1978 according to Muslim customs; their marriage was contracted in Siasi, Sulu with the consent of Sophia’s parents and a dowry of P5,000, and was later acknowledged by Sukarno as his wife.
The couple had a four-month-old son and lived with Sophia’s parents in Baliwasan Grande, Zamboanga City.
Sukarno was jobless and studying criminology while Sophia was attending a secretarial course; Sukarno’s known propensity for jealousy frequently led to quarrels between him and his wife.
Sukarno often threatened Sophia with a Batangas knife during their disputes.

On November 21, 1980, a serious quarrel occurred; Sukarno left the house with his son and later returned when fetched by Sophia and her sister.
On November 23, 1980 (a Sunday), Sukarno claimed he was going to Isabela, Basilan; however, later that day, Sophia and her sister witnessed him in the Rizal Theater, contradicting his stated alibi.
That same afternoon, while Sophia and her sister were in the movie theater, reports over the radio announced the discovery of a dead body at the funeral parlor, identified as Sophia.

Security guard Leovigildo Aquino, while on patrol near the Western Mindanao State University, heard a woman's cry ("Ay") and later encountered a half-naked, shirtless Sukarno near a jeep on Pitul Road.
Investigating the scene, Aquino and another guard found the body of a slain woman displaying multiple wounds: incised, punctured, and lacerated injuries, including wounds below the left nipple, on the abdomen, sternomastoid muscle, head, and neck.
A bloodstained Batangas knife, consistent with the one Sukarno used to threaten Sophia, was found approximately six feet from the victim’s body.
Other incriminating evidence included Sukarno’s “Citron” wrist watch—which he initially claimed was stolen—and Sophia’s purse found on his person containing eight pesos in coins.
Sukarno was observed covering Sophia’s dead body with his shirt and providing an account of being held up, a narrative later found inconsistent with the physical and documentary evidence (e.g., the logbook of the M/V Don Julio).

Sukarno testified that he had traveled to Basilan by boat (M/V Don Julio) with a cash transaction involving gold coins and that at the discotheque with his wife they were later held up by armed assailants.
His version claimed that during the robbery, he was beaten and stabbed, and that he managed to give his wife the money tied around his waist for her to escape as the robbers assaulted him further.
Witness testimonies and documentary evidence (e.g., the actual sailing times recorded in the ship’s log and the sightings at the theater) contradicted his assertions, thus labeling his story as “inherently incredible” by the trial court.

Despite his elaborate version of events, Sukarno’s behavior after the incident—such as his lack of communication with his in-laws, absence from subsequent funeral and mourning rituals, and his antagonistic remark towards Sophia’s family—further implicated his culpability.
The circumstantial evidence, including the physical evidence and contradictory timeline, led the trial court to conclude that Sukarno himself attacked and killed his wife.
